Protein Total, Serum

The Protein Total test measures the total amount of major proteins in your body, namely, albumin and globulin. It is also used to detect diseases related to improper protein metabolism and diseases that affect the liver, kidneys, or immune system. A higher than normal level of protein total in your body may indicate medical conditions such as viral hepatitis, cirrhosis, HIV/AIDS, multiple myeloma, etc. On the other hand, a lower-than-normal level can indicate conditions like liver disease, malnutrition, kidney disease, or an autoimmune disorder.

The Serum Albumin test measures the level of albumin protein in your blood. Albumin is one of the major proteins found in your body; about 60% of the total protein is made up of albumin, which is produced by the liver. It helps carry small molecules, such as hormones, vitamins, minerals, and medicines, throughout the body. It also serves as a source of amino acids for tissue metabolism. Albumin helps stop the fluid from leaking out of the blood vessels. When the albumin level is insufficient, the fluid can leak out of your blood vessels and build up in your lungs, belly, or other body parts.

The Globulin, Serum test measures the levels of globulin protein in the blood. Globulin is one of the major proteins (about 40% of the total protein) found in the body and is produced by the liver and immune cells. It usually exists in different forms: alpha globulins, beta globulins, and gamma globulins. These forms play an important role in liver and kidney functioning, blood clotting, and fighting off infections. 

The Albumin/Globulin Ratio, Serum test is performed if a liver or kidney disease is suspected. It quantifies the concentrations of two essential blood proteins, albumin and globulin. The test is a comparison figure in which albumin present in your body is divided by the amount of globulin to get the Albumin/Globulin) ratio. This ratio helps assess how well these two proteins are balanced and helps evaluate liver or kidney health.
